need e-trike advice (wife knee surgery)

[tarheelblue]

I would like to get my wife an e trike so she can still be out there riding as she recovers from ACL/MCL. she's nearly 5 months post now and itching to be mobile but still lots or recovery to go

what are the reputable brands? and ones that I can get serviced (or are easy to work on)? I would even consider a solid second hand trike. or ones to AVOID

I'm not wealthy so can't be dropping 2 grand either. which is mostly what I see out there. are there reasonable options under $1000? any help appreciated

cheers!
